Dr. Laby, an MD ophthalmologist and sports vision specialist, advises caution before starting sports vision training. He emphasizes that standard vision therapy may not benefit elite athletes with already good vision. The podcast highlights the importance of identifying specific visual deficits crucial for a sport rather than pursuing general enhancement with unproven benefits. Dr. Laby warns against unsubstantiated claims and the "buyer beware" nature of the sports vision training market, recommending a focus on credible sources and sport-specific training. He notes that current research lacks strong evidence linking enhanced visual skills to improved on-field performance.
